What kind of minority group?

They're religious kooks. That doesn't mean they deserve to be stamped out, necessarily, but they're also not a "minority group" by the common definition of the term.

How not? The Chinese government locks them up, murders them, and harvests their organs because they disagree with the communist party. Sounds like pretty classic "authoritarian government vs minority group" to me.

I don't think you engaged with my comment in good faith, here.

Falun gong are han Chinese who chose to identify with a particular religious offshoot. That doesn't make them a minority group as westerners understand it. Would you call Mormons minorities?

I think it is pretty common to refer to Jews or Muslims as minorities, and it doesn't seem weird to me to call Mormons a minority group as well.

Yes. I'm an American and America was founded by a bunch of religious offshoots who were being persecuted in their home country for being offshoots (protestants) rather than having the majority religion of their peers (Catholic). Religious minorities are minorities too.

In general, You are defining minority group as minority ethnicity only

Outside of Utah, yes.
